These extensions were previously in `pkg/analyzer_utilities`, which is not published on `pub`. That meant they could not be used from within the `lib` directory of any package that *is* published on `pub`. Specifically, they could not be used from within `pkg/analyzer_testing/lib`. In a follow-up CL, I will modify the testing logic so that after printing `To accept the current state, expect:`, it prints diagnostic codes in their proper camelCase format.
